Colibri EEPROM Layout

2026-07-28T16:06:18Z

Niclas: /* Vendor ID */

All the Colibri I/O modules come with a 1Mbit EEPROM on board, that serves to store a few different things;

* Vendor, Model and Revision of 'this' board.
* Calibration parameters needed to compensate for hardware tolerances.
* Test report (if any) from factory.
* The ''driver(s)'' (i.e. code) of the board, to be executed in the MCU module on behalf of the board.
* Any additional parameters, configuration that should survive over time.
* Any storage space an on-module co-MCU needs.

= Memory Layout =
The canonical memory layout is found in [https://github.com/currentmakers/colibri-runtime/blob/master/include/colibri-sdk/colibri-io-eeprom.h Colibri SDK GitHub repo].

"Reserved future use" means that the Colibri Runtime firmware may introduce features in the future that needs additional EEPROM space, and these regions MUST NOT be used by vendors.
"Vendor area" is guaranteed that the Colibri Runtime firmware will NOT use in the future, and vendors may use it any way they want.

[[Streamline Ethernet]] is an Ethernet port for the [[Streamline MCU STM32F407]] and using a LAN8742A PHY driver. STM32F407 has a MAC interface and
on this blade we are connecting up the RMII variant of that.
